On-demand loading of values from remote stores when an unknown value is set and queryMode = 'remote' and forceSelection = true

Creation of new value records for forceSelection false

Configurable pinning of combo pick list for multiSelect = true

Configurable rendering of labelled items (auto-sized or stacked)

As BoxSelect extends ComboBox, most (if not all) of the functionality and configuration options of ComboBox should work as expected

Lots more!

Any contributions of testing, improvements or other constructive feedback are greatly appreciated. I intend to actively maintain the development of this extension through the life of ExtJS 4, and will be able to best do so with the support of the community. Many thanks go out to everyone that has contributed already, and to those that will do so in the future.

Now on github!
